and had six children. Of the two sons, one died in infancy, 

 and the other, William F. Dreer, conducts, at 714: Chest- 

 nut street, the business which is incorporated in the 

 name of his father. Henry A. Dreer died of a nervous af- 

 fection of the heart. He was of modest temperament 

 and frail constitution, and confined himself to business 

 rather closely. He was liberal in public matters, but 

 always kept out of political life. He compiled several 

 small works in connection with the business, and wrote 

 frequently for the Weekly Saturday Evening Post, of 

 Philadelphia, and for Godev's Ladies' Magazine.

 Dew Plant. A very interesting group of insectivorous 

 plants. About 100 species scattered throughout the 

 world, except the Pacific islands, and most common in 

 Australia outside the tropics. Perennial bog herbs with 

 basal Ivs. clothed with glandular hairs, which secrete a 

 fluid that holds insects fast. Foliage and inflorescence 

 differ widely. The 3 species described below may be ob- 

 tained through dealers in native plants. For culture, 

 see DarUngtonia.

DRUPE. A fleshy fruit containing a single seed with 

 a bony covering or "stone," 

 as a plum. Fig. 742. A Drupe 

 resembles an akene in being 

 1-sided, and not splitting, but 

 an akene is dry instead of 

 pulpy or fleshy. The most 

 important drupaceous or stone 

 fruits are peaches, plums, 

 apricots, cherries and rasp- 

 berries. Each of the fleshy 742. Young drupes (apri-

DEt-AS (Greek, wood- 

 nymph). JtCosdcea. A genus of 

 2 or 3 species of dwarf, hardy, 

 tufted, evergreen, somewhat 



shrubby plants with oblong lvs. half an inch long, 

 recurved at the margins, shining above, snowy white 

 beneath, and large white or yellow fls. borne singly on 

 slender scapes: calj'x glandular-hairy: petals 8-9, 

 broadly obovate: stamens many. The genus is close to 

 Cieum.'but the species of Geum are herbs with deeply 

 cut foliage. J. W. Manning recommends a soil well 

 furnished with peat. 



Dryas octopetata requires a well drained, porous soil, a 

 sunny but not dry position. It is well to shade the foli- 

 age from bright sun during the winter months with 

 evergreen branches to prevent the foliage from having a 

 scorched appearance. A capital plant for the rockery. 

 Prop, by cuttings, division, or by seed.
